近年移动数据业务增速迅猛,而3G网络尚不成熟,大量数据用户仍以2G网络承载。详细分析了影响2G网络数据信道承载能力的主要因素,提出了通过现网统计参数进行PDCH(分组数据信道)承载能力的取定,以及分区域进行2G业务预测的思路,给出了信道资源配置规划的方法。通过此方法可进行PDCH需求、动静态PDCH及EDGE(增强数据速率GSM演进)载频配置计算。
In recent years, the rapid growth of mobile data services, while the 3G network is not yet mature, a large number of users still carry 2G network. The main factors that affect the carrying capacity of 2G network data channels are analyzed in detail. The idea of taking the PDCH (Packet Data Channel) carrying capacity and the prediction of 2G services in the sub-area through the statistics of the existing network is proposed. The channel resource allocation Planning method. This method can be PDCH requirements, static and dynamic PDCH and EDGE (Enhanced Data Rates for GSM Evolution) carrier frequency configuration calculation.
